Spent the day removing and strippng the wiper mechanism from SWMBOs Alhambra which had seized on the spindles (common issue according to various forums). Got the linkages free and re-greased all OK. mechanism now moves easily by hand, but the motor won't turn the mechanism despite working OK when not connected to the mechanism.

Can I assume the motor is damaged from trying to turn the seized spindles...? Can't see any obvious damage to the windings or control PCB.

A new one is £265 from EuroCarParts or a chance a 2nd hand eBay one for £65.

Have you checked that nothing else is siezed, or stopping the motor in some way. Just a thought. HTH Ray

Extensively - had the whole thing apart today and I can now rotate the complete mechanism easily by hand.

Just bought an eBay 2nd hand motor to see if that solves it - fingers crossed

Hope it all goes well. Cheers Ray
